IMIPRO'VEMENT IN SHOE-KNIFE AN D 'G-AUG-E.

The Schedule referred to in these 'Lettere Patent and making part of the same.

city of Syracuse, in the county of Onondaga, in the State of New York, have invented a new and useful Improvement on a Shoe-Knife and Gauge; and I do l hereby declare that the following is a full, clear, and

exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specica'tion, in which- Y Figure l represents a perspective view.

Figure 2 represents an inside View.

rFigure 3 represents. a portion of the handle.

Figure 4 represents a side View, showing the gauge to the knife-blade.` 4

Like letters represent `like parts.

Letter A represents the wood of the knife-handle.

Letter B, the knife-blade.

Letter G, the gauge on the end of the handle.

Letter 1)the screw. v

Letter E, the wedge.

Letter F, the thumb-screw.

Letter G, the metal frame of the knife-handle.

1. construct my shoe-knife and gauge of any suitaf ble material.

The metalframe, letters G G, is made as shown in iig. 2 of the annexed drawings.

Through one end of theframe is made a hole, through which a screw, of any desired length, passes.`

On the outside of the frame, and fastened to the screw, is a knurled screw-head, and on the inside of the frame is a collar on the screw, and playing against the frame, to keep the screw in position.

- Travelling on this screw is a slotted wedge, made as represented in iig. 2 of the annexed drawings.

Through the other end of the frame is a'slot, through which the knife-blade passes. 4

0n top ofthe knife-blade travels the wedge; by turning' the knurled screw-head, it forcesthe wedge against the knife-blade and frame, thereby clamping the knifeblade to any desired length.

On the saine end of the frame, but on one side, through which the'knife passes, is a projection, which forms a gauge, when trimming the sole-of'a booter shoe.

Theknife-blade is made of any desired width and length, and of a uniform size, andwithout any shank, so that either end can be used.

On each side of the ame,as shown `in iig. 4, ofthe annexed drawings, is wood fitted, of suitable size and thickness to form the handle, thereby forming the whole into any desired-size shoe-knife and gauge, with the knife-blade projecting out'of the handle only so far as the operator or. workman may desire. y

Instead of using in this handle a knifefblade, it can be used for any tool.

What I claim as my invention, and desire to secure The knife-blade B, gauge G, screw D, wedge E, and`
